"The remote SUSE Linux SLED15 / SLES15 host has packages installed that are affected by multiple vulnerabilities as
referenced in the SUSE-SU-2021:3451-1 advisory.

  - Uninitialized memory in a canvas object could have caused an incorrect free() leading to memory corruption
    and a potentially exploitable crash. This vulnerability affects Thunderbird < 78.13, Thunderbird < 91,
    Firefox ESR < 78.13, and Firefox < 91. (CVE-2021-29980)

  - An issue present in lowering/register allocation could have led to obscure but deterministic register
    confusion failures in JITted code that would lead to a potentially exploitable crash. This vulnerability
    affects Firefox < 91 and Thunderbird < 91. (CVE-2021-29981)

  - Due to incorrect JIT optimization, we incorrectly interpreted data from the wrong type of object,
    resulting in the potential leak of a single bit of memory. This vulnerability affects Firefox < 91 and
    Thunderbird < 91. (CVE-2021-29982)

  - Firefox for Android could get stuck in fullscreen mode and not exit it even after normal interactions that
    should cause it to exit. *Note: This issue only affected Firefox for Android. Other operating systems are
    unaffected.*. This vulnerability affects Firefox < 91. (CVE-2021-29983)

  - Instruction reordering resulted in a sequence of instructions that would cause an object to be incorrectly
    considered during garbage collection. This led to memory corruption and a potentially exploitable crash.
    This vulnerability affects Thunderbird < 78.13, Thunderbird < 91, Firefox ESR < 78.13, and Firefox < 91.
    (CVE-2021-29984)

  - A use-after-free vulnerability in media channels could have led to memory corruption and a potentially
    exploitable crash. This vulnerability affects Thunderbird < 78.13, Thunderbird < 91, Firefox ESR < 78.13,
    and Firefox < 91. (CVE-2021-29985)

  - A suspected race condition when calling getaddrinfo led to memory corruption and a potentially exploitable
    crash. *Note: This issue only affected Linux operating systems. Other operating systems are unaffected.*
    This vulnerability affects Thunderbird < 78.13, Thunderbird < 91, Firefox ESR < 78.13, and Firefox < 91.
    (CVE-2021-29986)

  - After requesting multiple permissions, and closing the first permission panel, subsequent permission
    panels will be displayed in a different position but still record a click in the default location, making
    it possible to trick a user into accepting a permission they did not want to. *This bug only affects
    Firefox on Linux. Other operating systems are unaffected.*. This vulnerability affects Firefox < 91 and
    Thunderbird < 91. (CVE-2021-29987)

  - Firefox incorrectly treated an inline list-item element as a block element, resulting in an out of bounds
    read or memory corruption, and a potentially exploitable crash. This vulnerability affects Thunderbird <
    78.13, Thunderbird < 91, Firefox ESR < 78.13, and Firefox < 91. (CVE-2021-29988)

  - Mozilla developers reported memory safety bugs present in Firefox 90 and Firefox ESR 78.12. Some of these
    bugs showed evidence of memory corruption and we presume that with enough effort some of these could have
    been exploited to run arbitrary code. This vulnerability affects Thunderbird < 78.13, Firefox ESR < 78.13,
    and Firefox < 91. (CVE-2021-29989)

  - Mozilla developers and community members reported memory safety bugs present in Firefox 90. Some of these
    bugs showed evidence of memory corruption and we presume that with enough effort some of these could have
    been exploited to run arbitrary code. This vulnerability affects Firefox < 91. (CVE-2021-29990)

  - Firefox incorrectly accepted a newline in a HTTP/3 header, interpretting it as two separate headers. This
    allowed for a header splitting attack against servers using HTTP/3. This vulnerability affects Firefox <
    91.0.1 and Thunderbird < 91.0.1. (CVE-2021-29991)

  - crossbeam-deque is a package of work-stealing deques for building task schedulers when programming in
    Rust. In versions prior to 0.7.4 and 0.8.0, the result of the race condition is that one or more tasks in
    the worker queue can be popped twice instead of other tasks that are forgotten and never popped. If tasks
    are allocated on the heap, this can cause double free and a memory leak. If not, this still can cause a
    logical bug. Crates using `Stealer::steal`, `Stealer::steal_batch`, or `Stealer::steal_batch_and_pop` are
    affected by this issue. This has been fixed in crossbeam-deque 0.8.1 and 0.7.4. (CVE-2021-32810)

  - When delegating navigations to the operating system, Firefox would accept the `mk` scheme which might
    allow attackers to launch pages and execute scripts in Internet Explorer in unprivileged mode. *This bug
    only affects Firefox for Windows. Other operating systems are unaffected.*. This vulnerability affects
    Firefox < 92, Thunderbird < 91.1, Thunderbird < 78.14, Firefox ESR < 78.14, and Firefox ESR < 91.1.
    (CVE-2021-38492)

  - Mozilla developers reported memory safety bugs present in Thunderbird 78.13.0. Some of these bugs showed
    evidence of memory corruption and we presume that with enough effort some of these could have been
    exploited to run arbitrary code. This vulnerability affects Thunderbird < 91.1 and Firefox ESR < 91.1.
    (CVE-2021-38495)

  - During operations on MessageTasks, a task may have been removed while it was still scheduled, resulting in
    memory corruption and a potentially exploitable crash. This vulnerability affects Thunderbird < 78.15,
    Thunderbird < 91.2, Firefox ESR < 91.2, Firefox ESR < 78.15, and Firefox < 93. (CVE-2021-38496)

  - Through use of reportValidity() and window.open(), a plain-text validation message could have been
    overlaid on another origin, leading to possible user confusion and spoofing attacks. This vulnerability
    affects Firefox < 93, Thunderbird < 91.2, and Firefox ESR < 91.2. (CVE-2021-38497)

  - During process shutdown, a document could have caused a use-after-free of a languages service object,
    leading to memory corruption and a potentially exploitable crash. This vulnerability affects Firefox < 93,
    Thunderbird < 91.2, and Firefox ESR < 91.2. (CVE-2021-38498)

  - Mozilla developers reported memory safety bugs present in Firefox 92 and Firefox ESR 91.1. Some of these
    bugs showed evidence of memory corruption and we presume that with enough effort some of these could have
    been exploited to run arbitrary code. This vulnerability affects Thunderbird < 78.15, Thunderbird < 91.2,
    Firefox ESR < 91.2, Firefox ESR < 78.15, and Firefox < 93. (CVE-2021-38500)

  - Mozilla developers reported memory safety bugs present in Firefox 92 and Firefox ESR 91.1. Some of these
    bugs showed evidence of memory corruption and we presume that with enough effort some of these could have
    been exploited to run arbitrary code. This vulnerability affects Firefox < 93, Thunderbird < 91.2, and
    Firefox ESR < 91.2. (CVE-2021-38501)
